← Nature & AnimalsWhich mechanism facilitates coral reef nutrient uptake when exposed to increased ocean acidity?
A)Enhanced denitrification by symbiotic bacteria✓
B)Reduced phosphate availability for zooxanthellae
C)Ammonia absorption by the coral host
D)Increased nitrogen fixation by cyanobacteria
💡 Explanation
Enhanced denitrification reduces excess nitrogen inputs when ocean acidification stresses coral; this symbiotic denitrification process helps maintain nutrient balance, therefore reducing harmful algal blooms, rather than exacerbating them like other choices.
